Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/libcrypt-des-perl-2.07/_des.c Examining data/libcrypt-des-perl-2.07/_des.h FINAL RESULTS: data/libcrypt-des-perl-2.07/_des.c:529:18: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. static unsigned char shifts2[16]={0,0,1,1,1,1,1,1,0,1,1,1,1,1,1,0}; data/libcrypt-des-perl-2.07/_des.h:1:18: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
